Boarding Group

A boarding group is an assigned sequential tier that determines when a passenger may join the line and walk through the jet bridge to board an aircraft. Rather than releasing all passengers at once — which would create a chaotic rush — airlines divide the cabin into numbered or lettered waves and call each group individually, typically at two- to four-minute intervals.

What Is a Boarding Group?

A boarding group is a number, letter, or label printed on your boarding pass or displayed in an airline app that tells you which wave of passengers may approach the gate when your identifier is called over the public address system. Most major carriers use between four and six distinct groups on domestic flights, while long-haul international flights with multiple cabin classes may have seven or more. The system exists because boarding a narrow-body aircraft with 150 passengers simultaneously would take far longer than a structured sequential process.

How It Works in Practice

Airlines assign boarding groups at the time of check-in or, for elite members, at the time of booking. Gate agents call groups in order — typically starting with passengers who need extra time, then first class, then business class, then elite frequent flyers, and finally economy in subdivided groups from the rear of the aircraft forward. American Airlines uses numbered groups (1 through 9), United Airlines uses boarding groups labeled by fare product and status, and Southwest Airlines famously assigns A, B, and C groups with numbered positions (A1 through A60) and uses open seating within those groups. Delta's boarding process starts with Delta One, then First Class, then Diamond and Platinum Medallion members, followed by Sky Priority, then Main Cabin 1 through 3.

Why It Matters

Boarding order affects passenger experience in tangible ways. Passengers in early groups board before overhead bin space fills up, reducing the risk of having to gate-check a carry-on bag. Families and parents with young children often receive pre-boarding privileges separate from the group structure. For airlines, structured boarding reduces total boarding time, directly enabling faster aircraft turnarounds — a critical efficiency metric for carriers whose aircraft sit on the ground earning nothing. Studies by researchers at Purdue University and Mythbusters-style analyses have consistently shown that random or rear-to-front boarding outperforms traditional front-to-back boarding in total elapsed time, prompting airlines to experiment with outside-in (window seats first) and random-within-zone methods.

Key Facts and Figures

• American Airlines' group system spans 9 groups plus pre-boarding, making it among the most segmented domestic boarding processes.
• Southwest Airlines' open seating model eliminates assigned seats entirely; boarding position A1 is among the most coveted perks of early check-in or elite status.
• FAA regulations require airlines to give pre-boarding to passengers with disabilities under 14 CFR Part 382.
• Alaska Airlines uses a zone system (First Class, MVP Gold, MVP, Main Cabin 3, 2, 1 and Basic Economy) with window-seat priority.
• Average domestic boarding time across US carriers is roughly 20–30 minutes for a full narrow-body; inefficient boarding can add 10+ minutes.
• Basic economy fares on most US carriers are assigned to the last boarding group, incentivizing passengers to pay for seat selection or status upgrades.
